Historical Treaties of Southeast Asia

A research program in global diplomatic history

Historical Treaties of Southeast Asia is a collaborative research program in Global Diplomatic History financed by the Swedish Research Council and running from 2022 until the end of 2027.

A team of seven researchers based in Europe and Southeast Asia investigate the role of treaties and treaty-making in the imperial expansion and colonisation of Southeast Asia from the eighteenth to the early and twentieth century.

The researchers systematically analyse all bilateral treaties concluded between a European, American or Japanese imperial power and a Southeast Asian polity between the eighteenth and early twentieth century. In addition, a selected number of diplomatic treaty-making processes are studied in detail. In doing so, the project aims to bring about a new and more nuanced understanding modern imperialism of relevance not only to Southeast Asia but globally.

On 2 April, Maarten Manse will present his forthcoming book Empire of Improvisation: Taxation and Governance in Colonial Indonesia at KITLV in Leiden. The book examines how colonial authorities in Indonesia developed flexible and improvised systems of taxation and governance, revealing how everyday administrative practices shaped the functioning of empire.

Published by Brill in 2026 as part of the Verhandelingen van het Koninklijk Instituut voor Taal-, Land- en Volkenkunde series, the study offers a new perspective on colonial state formation and the production of fiscal knowledge in Southeast Asia.

This seminar is a hybrid event and will be held in the conference room of KITLV, Herta Mohr building, room 1.30, Witte Singel 27 A, Leiden and online via Zoom. Registration is done through KITLV’s website.

Treaties and Origins of the Cambodia-Thailand Border Dispute

Ever since Cambodia became independent in 1953, its border with Thailand has been contested, the ancient Hindu temple Preah Vihear (or Phra Wihan in Thai) being a particular source of discord. To understand the present conflict, it is necessary to look at two treaties concluded in 1904 and 1907.
